Technical details

The vulnerability is a deserialization flaw in PRISMAproduction that permits remote code execution. An unauthenticated attacker positioned on an adjacent network can exploit this weakness without requiring user interaction or special conditions (AC:H and UI:N per CVSS v3). The attack requires network adjacency (AV:A), suggesting the system must be on the same local network segment. Successful exploitation grants the attacker arbitrary code execution capabilities. A patch is available in version 6.5.1 and higher, requiring assistance from Canon Service & Support for installation.
